We found therapeutic benefit of real acupuncture for neuropathic pain that is consistent with previous pilot acupuncture CIPN trials. Distinctively, our study is the first, to our knowledge, to incorporate a sham treatment and a nontreatment control to evaluate the efficacy of acupuncture for CIPN.

The addition of a sham acupuncture control in an acupuncture clinical trial is difficult owing to the challenge of incorporating a truly inert placebo. In addition, a sham control limits the ability of a small effect size to elucidate a true difference between real and sham acupuncture.

Not only did our study demonstrate the feasibility of conducting a sham-controlled acupuncture trial, it generated sufficient pilot data to inform a definitive sham-controlled efficacy trial. Our trial is limited by its small sample size, single center, and short-term follow-up.
